Motivaciones de la violencia de pareja en hombres y mujeres detenidos por violencia doméstica y remitidos a programas de intervención para maltratadores: “Los resultados de este estudio sugieren que los hombres y las mujeres detenidos manifiestan motivos similares para la…
Very excited to share our new preprint from the Kirkpatrick and @arbelharpak labs! Natural selection can act differently on females and males. How frequently does this happen in the human genome? biorxiv.org/content/10.110… 1/n
(D) Even if false discoveries were not a concern, it is not clear that the method would identify the correct time period of selection. The paper does not adjust for ancestry proportions or PCs, the approach taken in prev. papers. 15/
Pervasive findings of directional selection realize the promise of ancient DNA to elucidate human adaptation biorxiv.org/cgi/content/sh… #biorxiv_evobio
It took me SEVEN years to figure out that you can save a ggplot as a vectorized .svg file ggsave("file.svg"). The svg file can be opened on powerpoint and it will be completely vectorized, even text are still recognized as text boxes! No more recreating plots on illustrator!!!!!
Polygenic scores explained in two slides 🧬
IMHO, I think this is one of the main flaws of classic Evolutionary Psychology when it tries to explain individual differences; when its main framework was developed, they didn't know how polygenic human traits were. Having many genes with small effects influencing human…
Ok, now I understand your question, which is a very good one and goes into the fundamental question of why polygenicity is so pervasive, "who cares if you have a +1SD allele or 10 x +.1SD alleles, trait is the same." Effect sizes can matter a lot. Intuitively, they wouldn't…
This comment reminds me of an excellent paper by Arbel Harpak and Molly Przeworski "The evolution of group differences in changing environments" journals.plos.org/plosbiology/ar…, where the same temporal polygenic shifts in allele frequency can be observed in either: Case 2: "increase in…
Diego Londono-Correa @dielondono and Camille Williams then gave a talk on their work on the genetics of externalising behaviours, associated with risk taking, and finding mixed positive and negative signals of selection
It's a nice paper, but I disagree with one premise about balancing selection. Here, Zietsch argues that “There is no evidence that balancing selection has substantively shaped complex traits”. There is evidence challenging this. Many studies on the selection of human complex…
WHY DO WOMEN CHEAT? Multi-national quant/qual retrospective study tested between theories (n=254 cheaters). Some support for dual mating (women want affair partner's good genes + current partner's good parenting), challenges to mate-switching hypothesis sciencedirect.com/science/articl…
Few evolutionary psychologists engage with the modern genomic literature. Brendan Zietsch is an exception and he has a new paper out, criticising explanations for heritable variation based on balancing selection. He's pulling no punches.
Last week, with Marco Del Giudice and @emanuele_espo98 we hosted a workshop in Erice, Sicily: ‘Bridging evolution and genetics’ to understand mental disorders. It exceeded our expectations! I’ll run through the presentations…

¿Existe la ciencia en Colombia? lasillavacia.com/opinion/existe… "El principal obstáculo es que no se valora la ciencia, se le confunde con otras áreas del campo humano, se desprecia a los investigadores, y en cambio se le da el nombre de “ciencia” a asuntos que no lo son."

“The PGS for morningness significantly predicted morningness (R2 = 1.55%) and depressive symptoms (R2 = 0.22%).” I always feel like I am missing out something as to why we should care about such tiny associations in these studies? journals.sagepub.com/doi/10.1177/07…
“Study doesn’t turn you into a genius, it turns you into an expert” is a really strong explanation of the diff between fluid and crystal intelligence.
